INTRINSICALLY SAFE

PRESSURE CALIBRATORS

The 725Ex is an intrinsically safe

multifunction process calibrator
for usage in areas where explosive
gasses are known to be pres-

ent. This calibration tool sources
and measures almost all process
parameters. Add any of (8) 700PEx

pressure modules to make the
725Ex a pressure calibrator.

The Fluke 718Ex is a powerful

intrinsically safe self-contained
portable pressure calibrator for
usage in explosion endangered

areas. It provides a total pressure
calibration solution for transmit-
ters, gauges and switches. This
compact pressure calibration

solution is about a third of the size
of comparable instruments and
weighs just one kilogram (two

pounds). The unique easy to clean
pump helps protect the pump from
damage and provides the ability to

service the pump without disas-
sembly, even in the field.

The Fluke 700PEx Series

Pressure Modules allow you
to measure pressure with Fluke
intrinsically safe calibrators such

as the 718Ex and the 725Ex.
The pressure modules measure
pressure using an internal micro-

processor. They receive operating
power from and send digital
information to the intrinsically

safe calibrators.

The Fluke-700G Series test gauges also have an IS
rating. See previous page for more information on

these gauges.
